574 MR. D. G. ELLIOT ON THE GENUS PELECANUS. [Noyv. 25, 
the O. hernandezii as the type—this, however, being a synonym 
of P. thagus of Molina, now accepted as P. moline of Gray. 
P. rufescens in this article is also renamed pheospilus. Species 
eight. 
“(1836.) Brandt, Joannes Fredericus, ‘ Descriptiones et Icones Ani- 
malium Rossicorum novorum.’ The author gives in this pamphlet 
descriptions and copious synonymy of two species, P. onocrotalus 
and P. crispus, while fuscus is attributed to the West Indies, and 
conspicillatus to New Holland, and onocrotalus, vel species valde 
affinis to North America. A good description of the bony structure 
and internal anatomy of onocrotalus is added. A very valuable 
contribution. 
(1837.) Riippell, ‘ Museum Senckenbergianum,’ p. 185. A new 
species is here described as P. minor. Species nine. 
(1838.) Lichtenstein, ‘Abhandlungen der Kénigl. Akademie der 
Wissenschaften zu Berlin.’ In this valuable paper is contained the 
best monograph of this genus that had thus far been attempted. 
Seven species are given, namely, onocrotalus, mitratus, crispus, 
rufescens, trachyrhynchus, fuscus, and conspicillatus: P. mitratus 
is described as new, but is the minor of Riippell given in the pre- 
vious year, as above noted, while philippensis of Brisson and manil- 
lensis and roseus of Gmelin are considered the same as rufescens. 
A plate with representations of the heads, both in profile and front 
view, of six of the species is given, conspicillatus having been 
omitted. Altogether it is the most valuable paper on this genus 
thus far published. 
(1849.) Gray and Mitchell, ‘Genera of Birds.’ ‘The genus Pede- 
canus is here introduced as belonging to the second subfamily of 
the great family Pelecanide, which arrangement the present writer 
accepts only in part. The four generally considered families, Pele- 
canide, Plotide, Tachypetide, and Phalacrocoracide, would seem 
to be far more naturally arranged if brought together under the first 
named, and these divisions considered as subfamilies of the one 
family Pelecanide. The differences exhibited among the members 
of each group from those of the others are more of the kind pro- 
perly considered generic than of those which constitute separate 
family divisions. All the species as now known are included in this 
excellent list, except the P. javanicus of Horsfield. 
(1850.) Reichenbach, “ Novitiee ad ‘Synopsis Avium.’”’ Eight 
species are here enumerated, javanicus and moline being omitted. 
Reduced figures are also given. 
(1851.) Reichenbach, MS., as quoted by Bonaparte. Four ge- 
nera are here instituted—Catoptropelicanus, type P. conspicillatus ; 
Onocrotalus, type P. crispus; Cyrtopelicanus, type P. erythro- 
rhynchus ; and Leptopelicanus, type P. fuscus. 
(1857.) Bonaparte, ‘ Conspectus Generum Avium.’ In this 
monograph the various species are grouped in three genera. Pele- 
canus, Linn., comprises conspicillatus, crispus, rufescens, philip- 
pensis, and onocrotalus. Catoptropelicanus, Reich., is placed as a 
subgenus for conspicillatus, and Onocrotalus of the same author as a
